Title: Device and method for measuring ice making of ice heat accumulation device
Inventor: NAKAZAWA YUJI
IPC: G01N21/85
Filed: 1991-08-30
Abstract: PURPOSE:To enable ice formation and the amount of produced ice to be measured continuously in a dynamic ice heat accumulation device. CONSTITUTION:An ice mixture side potential difference measuring means 25 measures potential difference  V2 between ice mixture side detection electrodes of a circulation path 6 on the downstream side of a liquid-separation portion 11. On the other hand, a potential difference measuring means 30 measures potential difference  V1 between the liquid side detection electrodes of a branch path 18 on the liquid side. An ice-making calculation means A1 obtains the voltage difference ( V2- V1) based on  V2 and  V1. Then, formation of ice is detected by the operational expression,  V2- V1=AI/(1-c) (A: proportionality constant, I: current, c: ice-making rate). Also, the ice-making rate is calculated corresponding to this voltage difference and the amount of ice made is calculated by considering the flow rate of coldness-accumulation material W.

Title: Portable telephone set
Inventor: SHIOBARA TOSHIHIKO
IPC: H04M1/00
Filed: 1998-08-04
Abstract: PROBLEM TO BE SOLVED: To release external force exerted to the portable telephone set and to obviate defects by delivering a variable voltage signal to a control means, in response to the strength of the external force and driving a notice means, if the voltage signal is at the outside of a specified value set arbitrarily in advance by the control means to notify the user about the occurrence of deformation resulting from the exerted external force. SOLUTION: A projection section 8 is projected in the form of contact with a surface of a pressure-sensing element 1. A projection section 9 is projected from a case 6 on the other side of a printed circuit board 7 to which the pressure-sensing element 1 is connected, and the projection sections are placed to clamp the pressure-sensing element 1 inbetween. When an external force is exerted on the case 6, the projection section 8 of the case 6 receives the external force to press against the pressure-sensing element 1.  The pressure-sensing element 1 delivers a voltage signal to a control section in response to the strength of pressing, that is, the magnitude of the external force, the control section compares the voltage signal with a value arbitrarily preset arbitrarily to control a notice section, which notifies the user to the effect that the portable telephone set received external pressure higher than the value set. Thus, defects of the portable telephone set due to the external pressure are surely prevented.

Filed: 1997-08-15
Abstract: PROBLEM TO BE SOLVED: To apply this method to a feeding path by utilizing in duplicate a user side and a base station or base side antenna to avoid the use of a filter for signal area separation. SOLUTION: A data stream D1 sent from a base station is given to a FIFO to produce a gap pause period.

A user side control circuit St2 is normally in a received state, and the circuit St2 is switched when there is the gap pause period in the data stream of the circuit St1 or a user switching request is in existence in the data stream. The switching signal from the circuit St1 to a converter unit is sent via an HF feeder line by various voltages similarly to the case with reception polarization changeover of a satellite equipment. Thus, only a sole line is required to the converter unit at all times.

Title: Photoelectromotive force element
Inventor: FUKATSU TAKEO
IPC: H01L31/04
Filed: 1984-10-19
Abstract: PURPOSE:To prevent loss of an optical carrier formed in the vicinity of a back surface electrode, by providing at least a double-layer structure for the back surface electrode, and making the work function of the back surface electrode layer, which is contacted with a p type layer, to be 4.5eV or more. CONSTITUTION:In a photoelectromotive force element, in which a semiconductor layer comprises an amorphous semiconductor and especially the light incident side is an n type layer, a first back surface electrode layer 25 has a work function of 4.5eV or more. As a metal material suitable for the element, e.g., gold is used. As a second back surface electrode 25b, e.g., silver or aluminum, whose light reflectivity with respect to light having a long wavelength is larger than that of the first back surface electrode layer 25a, is used. Since the work function of a p type layer 24 is the same as that of the first surface electrode layer 25a, a barrier against holes generated at their boundary is small, and the light carrier can be effectively collected on the back surface electrode. The light having the long wavelength, which is included in the incident light, is hard to be absorbed in the semiconductor layer. The long wavelength light, which is transmitted through the first back surface electrode layer 25a, is reflected by the second back surface electrode layer 25b and returned into the semiconductor layer. Said light contributes to the generation of the light carrier.

Abstract: PURPOSE:To prevent explosion and to conduct stabilized forced cooling by providing an atmosphere isolating device at the passage of the cooling zone of an annealing furnace, the quenching gas force-feeder and heat exchanger in a box to be supplied with an inert gas outside the cooling zone and a quenching gas injector. CONSTITUTION:A strip 7 is heated, soaked and then cooled to an overageing temp. In this case, the strip is cooled in the cooling zone 3 of an annealing furnace having an atmosphere isolating device 10 at its passage. At this time, the inert gas is cooled by a heat exchanger 15 set in a box 13 charged with an inert gas such as gaseous N2, and a quenching gas such as gaseous H2 freed of air and with its pressure increased is sent to an injector 16 having a gas force-feeder 14 and injected on the strip 7 to forcedly cool the strip. In this case, gaseous H2 is freed of air, the atmosphere of the cooling zone 3 is isolated from the adjacent soaking zone and overageing zone 4, and hence the infiltration of the atmosphere in the other zones or air into the cooling zone 3 is prevented. Accordingly, explosion is completely prevented, and forced quenching is conducted.
